Am I an idiot for wanting to boost a high compression 318?

I bet no one on this thread has ever built a high compression boosted engine. If you have please chime in. I’ll wait.

It’s 100% doable and I’ve done it. And I am currently doing it. Two things have to happen. You have to have a fuel with enough octane. PERIOD. I recommend e85. And you have to have your tune up spot on. At 5000 ft elevation there will be a little larger tuning window. 8.5:1 and 20 psi is no different than 10.5:1 and 5psi. Cylinder pressure is cylinder pressure I don’t care how you get there. As you go up in compression the tuning window gets tighter and tighter and the engine becomes more rowdy. If the ring gaps are tight now don’t even think about boost. 4psi at 10.3:1 will make enough heat (especially with a supercharger) to stick a ring and break the ring land. One more thing, intercooling is not an option it’s a necessity. Good luck.
